> But then, you just don't learn regex. So where does the intuition for what regex can do come from?
The training data is there for regex and it's unlikely that regex will experience massive changes but your concern makes sense. I had to learn before LLMs handled that part, the "when to use this" intuition. My guess would be that the logical conclusion is dependence on LLMs to make that determination increasing over time, both for when and how to use regex, for better or worse.
